On the basic of former engine, the angle variable partial program of the fan and compressor guide vane of engine mathematical model is been renewed.
在原发动机模型的基础上，补充编制了发动机数学模型的风扇和压气机导叶角度可调的部分程序；
2
Cylinder profile has little influence on shaft power of rotary vanecompressor.
型线的构成对压缩机轴功率的影响可以忽略。
3
It is shown that the model in this paper reflects the dynamic working variety of the compressor, and it is similar to the fact of the rotary vanecompressor.
